A Functional Above-the-Knee Prosthesis
The widely used above-the-knee prosthesis is composed of a quadri lateral muscle-contour, wooden thigh socket, a knee mechanism, a wooden shank, a SACH foot, and a suitable pelvic suspension. This type of pros thesis has met with considerable success in most patients, but it is expensive and not all geriatric patients can wear it. A so-called temporary limb—a modified long brace with a leathe...
متن کاملBiomechanics of the through-knee prosthesis.
The biomechanics of the through-knee prosthesis is considered in detail and comparisons made with the above-knee case. Socket shape and suspension are discussed and comment offered on knee function in both stance and swing phases.
متن کاملBouncy knee in a semi-automatic knee lock prosthesis.
The Bouncy Knee concept has previously proved of value when fitted to stabilised knee units of active amputees. The stance phase flex-extend action afforded by a Bouncy Knee increased the symmetry of gait and also gave better tolerance to slopes and uneven ground. A bouncy function has now been incorporated into a knee of the semi-automatic knee lock design in a pilot laboratory trial involving...
متن کاملAlignment of the above-knee prosthesis.
Alignment will be discussed in terms of what happens as a result of specified changes in the relative positions of the prosthetic components. As a person walks on his prosthesis the conditions which predominate at various stages can be identified: (a) the conditions of no-load, or swing phase, (b) the conditions under which there is full loading or stance phase, (c) the capacity to control the ...
متن کاملThe TC double socket above-knee prosthesis.
The conventional total contact suction AK prosthesis presents several disadvantages, such as difficulty in wearing the socket in a sitting position, difficulty in obtaining a favourable disposition of the stump soft tissues in the socket and difficulty in avoiding stump perspiration problems. In an attempt to solve these disadvantages, a new AK prosthesis with a thermoplastic double socket was ...
